RetailMeNot is the easiest way to gain instant access to coupons and great deals from 100s of your favorite stores. They have both a web and mobile app to allow you to snag a deal whether your at home or on the run. 

My objective was to create a icon set that could be used for both their web and mobile apps that had a fun and friendly vibe that paralleled their current brand. They requested standard interface icons as well as category icons to represent the different areas of savings that they offer.
